[solved] Implementing 2D platformer wall jumping

Newbie & Debugging Questions
#1

Hey JGO, I got bored and decided to goof around and make a player that has physics. (Mass, gravity, velocity etc)

I’m wondering how would I implement wall jumping?

(Video on what I’m talking about: Short youtube video)

Here’s a picture, if anyone needs code snippets from the platformer let me know :slight_smile:

Code snippets:


/** Update method */
public void tick() {
	// Handles w,a,s,d, space_bar etc
	processInput();

	// Handles jumping/falling/velocity etc
	processPhysics();

	// Handles collision (x<=1 etc)
	processCollision();
}



/** Process collision method */
private void processCollision() {
	// Player has somehow reached top of level o.0
	if(y <= 0) {
		y = 0;
		jumping = false;
		jumpTimeSoFar = - 1;
		jumpTimeStart = - 1;
		jumpTicks = 0;
		fallTimeSoFar = - 1;
		fallTimeStart = System.currentTimeMillis();
		falling = true;
	}
	if(x <= 1) {
		// Player is touching the left wall
		x = 1;
		leftWallCollision = true;
	}
	if((x + width) >= (Launcher.WIDTH - 11)) {
		// Player is touching the right wall
		x = (Launcher.WIDTH - 11) - width;
		rightWallCollision = true;
	}
}

Thanks for any help/feedback JGO, I only found 1 post on our forums relating to wall jumping and I took all the knowledge I can from it and am now stuck :S
